To all whom it may concern:.

Beit known that we, CHARLES M. CoNK- LIN and Emwnn H. LUNKEN, citizens Ofilte 10 have invents certain new and useful Im provements in Fire roof WindowConstruction of which the f lowin is a specification.

'sure relieved to ceivin T e said invention re ates to improvements in firefproohwindow construction and includes the ollowmg objects. First, to pro vide uide stri su OIlWlllCh the swingin sash g g g is mounted, w ic may be pressed outward into tight contact with themain frame or casement when the window is closed to make an exceedin 1y tight weather-proof joint, may be slight y spaced therefrom or the preserrnit the sash to be readil raised or lowere or may be withdrawn sufii ciently to disengage them entirely from the easement to permit the sash to be swung u on its horizontal pivots for the pur oses o cleaning, and ventilation. Secon to provide means by which said guide strips maybe simultaneouslyoperate from manipulating mechanism carried by the sash and, to adapt one of the manipulating devices to serve as a sash lock or fastener when the window is closed and the ide strips are ressed into tight cont/act wit the easement. bird, to provide a sash frame made of two parts separably connected togetherso that the glass ma be inserted laterally into the rec annel of one part and the other ap lie thereto and quickly and securely loc ed in position to confine the glass in place the parts of the sash frame being readily separable to allow the lass to be renewed in case of breakage.- ourth to rovide a sash of separably connected holow parts forming a frame with a plurality of air spaces and intermediate bracing webs thereby securing maximum strength an n idity with a minimum amount and weight 0 material.

With these and various other minor objects in view, the invention includes the vanous novel features hereinafter described and particularly set forth in the appended claims.

Referrin by reference characters to these drawings i ure 1 represents a front elevation part1 roken away, of the lower sash frame to i lustrate the application of the invention to the lower sash, the casing and upper sash being omitted in rider to show the parts on a scale sufficiently large to make the drawings clear. Fig. 2is a cross section on line 2-2 of Fig. 1 together with a portion of the outer frame groove. Fig. 3 18 a vertical section on line 3-3 of Fig. 1, looking toward the left and showing the lower portion of the upper sash. Fig. 4 is a vertical section on line 4-4 of Fig. 1 to ether with a portion of the sill. Fig. 5 is a etailed view of operating connections. Fig. 6 is a view of a modification. Fig. 7 is a cross section on line 7-7 of Fig. 1. Fig. 8 is a detailed view of one of the Looking strips. Fig. 9 is a longitudinal section through one of the side bars of the sash frame. Fig. 1Q is a sectional detail of a modified form of operating connections; Referrin by reference characters to these drawings, t e numeral 1 designates the window frame or casing and 2 the window sash. Both of these parts are constructed of fireproof material, preferably of sheet metal, and the window frame or casement is provided with vertical channels 3 which are preferably formed integral with the plate of the frame 1 and in which the sash uiding strips ma slide vertically. The sea es are supporte by the sash cords 4 counterbalanced b w ights in the usual manner, but as they orln no part of the present invention, the weights and sash cord guides are not shown herein. The sash cords are connected to eye ieces' 5 in which are journaledthe hinge plntles 6, upon which the sash frame hinges. The sash frame, the particular construction of which will be hereinafter described in detail, is rovided in its side edges with channels whic receive the guide strips 7. These may be plain channel strips and their edges are inclined inwardly as shown at 7 to coact with correspondingly inclined portions 3 at the edges of the c annel portion 3. The

rods 8 at the top and bottom of the sash-are durable sash, but one in be readily replaced when desired.

. rial, 11, and

action, thus permitting the sash to be raise and lowered 1n the ordinary manner. When,

however, the sash is to be swung horizontally upon its'pivots 6, further movement of the manipulating devices will draw further upon the rods and move the guide strips 7 inwardly sufficiently far to cause their inclined edges to completely clear the inner faces" of the window frame or casement, thus enabling the sash to be readily swung to any desired position.

The preferred construction of sash frame is shown in detail in the sectional views and comprises two hollow sheet metal parts, as 9 and 10 see Figs. 2 and 9. Each of these is preferably formed of a single piece of sheet metal folded upon itself in the shape shown, the two pieces being brought together, with their faces 9 and 10 in contact. These faces have portions alternately struck up and depressed with openings in each at the points of junction of the de ressed portions with the raised portions, an the raised portions of one bar 9 for example, are arranged in alinement with the deIpressed portions of the other bar 10. Thus w en the two parts, or bars are placed with their faces in contact, a locki bar 11 shown in detail in Fig. 8, ma be sli longitudinally into the space fornfe by the overlapping struck up portions and thus securely lock the two portionsor bars of the frame together. The bars are provided with projecting or flanged portions 9 and 10", respectively, the latter being ofiset to provide a space for the reception of the edge of the glass.

It will be understood that the side and cross bars are mitered and welded together it the corners, and where the sash includes a muntin, this also is welded to the cross bars. This provides two in rigid frames, a front one and a back one, which, when locked together by the locking bars as above described, in e an exceedingly strong and The space formed between the flanges 9 and 10 is of greater thickness than the glass for the-reception'of aclti or fillin -mate- 12 an it wil be readr y seen that the glass is easily and quickly applied by nserting it and the packing strips in place against the fla es 1Q before the removable frameis appli and locked in 'tion.

The filling material 111 whic lies against one face and the edge of the glass ma be putty, cement, or any suitable materia but we prefer to make the layer 12 of a channel wh'i the glass may,

. the'bottom bar of the sash. The fol more shape or folded stripfof spri brass, this stri being located on the side of t e glass towar s the removable frame part. The folded over edges 9 and 10 form the side bearing for the guide strips and from the manner in which these are folded it will be seen that extra thickness of material is provided atthis point, thereby not only securing additional strength, but avoiding the necessity of rivetlng the parts. In theslgace formed between 7 the inner and outer wal of the side bar 10 is located a block 13 to which the pivot pintle 6 is connected, this passing through an openi in the glliide strip 7.

ere t e window is provided with a muntin the two frame parts or bars 9 and 10 (Fig. 7) are made of substantially similar shape, the one having a central grojecting ortion 10 to properly space the a es to.

orm the glass receiving channels, an pro- 35 vide the overlapping portions for the reception of the bar.

The folded edges 9' and 10' are made to conform so far asexterior finish is concerned, to the edges of theopposite flanges and for this glurgose the outer layer of metal is bro t own to and folded around the edge of t e inner layer, which latter is bent slightly outward and into the shape shown.

Another advantage in the special con- 5 struction of sash frame above described is that it provides a hollow sash frame with a plurality of air chambers and with internal racing webs or members as the innnr walls, which serve as the means for connecting the 100 two parts serve also as bracing or strengthening webs, thus permitting us to secure maximum strength with the minimum thickness or weight of material. The meeti rails are constructed in substantially the same manner, being only modified to provide the necessary different shape or configuration of the exposed parts. 11 these no edge channel is necessary and consequently t e folded over portions 9 and 10 are brought into juxtaposition to provide a flush and substantially continuous surface as shown in Fig. 3. A metal packing stri 14 is secured to each meeting rail prefera 1y by having its curved edge bent around the portion 9 .a-nd

held by the clamping strip 14. The clamping Stl'lfi for the lower meeting rail of the upper sas is substantially the same shape as that 9f the upper rail of'the lowersash except that it has an lnwardly projecting guard por- 1 0 tion extending into the space between the twosashes.

The bottom cross bar or member of the lower sash is modified to adapt it to make a tight 'joint with the window sill, which is shown at 15. This latter, which is also preferablg of sheet metal is provided with a cen tral ange or rib 16 which enters a. space or channel 17 between the respective arts of (led over edges 10' support and hold in position a spring brass packing strip 18 which coacts with the ribor flange -16 to make atight and weather-proof joint-.lThis construction of the lower sash bar, in'conjunction with the particular shaped the window sill, enables us to secure ventilation without the entrance of rain, snow and directdrafts, as by raising the window onl a slight distance-a circuitous air passage is ormed. The inner wall 16 serves to deflect the incoming air u .wardly and in conjunction with the rib or ange 16 effectually prevents entrance of rain or snow.

It may be noted that in all of the bars constitutin the frame there is a slight space between t e ends of overlappin portions as clearly shown in Fig. 9. This al ows the members to accommodate themselves to any slight irregularities in manufacture, and provi es for any relative movement due to expansion and contraction.

The manipulatin device for operating the rods 8-at the to o the lower sash is preferably constructe so as to perform the double function of 0 erating the rods 8 and serving asa sashloc To secure this we provide a thumb lever 19 carried by a pivot pin 20 journaled in a block or plate 20 secured in the upper bar. The thumb lever has a pro'ecting arm 21 desi ned to engage a:recess in a eeper 22, secure by means, such as a screw 23, to the bottom rail of the upper sash. The inner ends of the rods 8 are attached by means of suitable eccentric connections to the in 20 within the hollow portion of the cross ar. These connections are such that when the arm 21 is in lockin engagement with the kee or 22 .the rods wil be ressed outwardly an the guide bars forced into rweathertight engagement with the window casement. When, however, the arm 21 has been moved sufiiciently to disengageit from the keeper so that the sash is free tobe raisedor lowered, the bars 7 will have been withdrawn by the rods only to-such a degree that-while friction is avoided, they still serve as guides 'for the sash in its vertical movement. When, how ever, the sash is to be swung upon its horizontal pivots, the arm 21 is moved still further and the guide bars withdrawn to a still greaterdegree into the channels in the side are of the sash frame. The manipulating dev1ce.for the rods in the bottom rail of-the sash, frame o crates in substantially the same manner, ut is located upon the front face of the sash frame and comprises buta single arm 21 carried b the pivot in 20 which extends through t e front wal of the barand .to which on the-inside the lower rods 8 areeccentrically connected. Instead of having an independent-operate mg or manipulating device for each set of rods we may connect them .by .a and running through one of the vertical members of the sash, and have the manipulating handle lohaving sash cated on either cross bar desired. Such a construction is shown in Fig. 10 in which the pivot pin 20 is continued in the formiof a rod 20' through the central muntinandjnto the lower bar, where it is caused to operate the rods by suitable eccentric connections similar to those of the up er bar. This may of course be arranged eitl ier with or withoutthe locking feature.

It will be understood that substantially the same guide bars, rods and manipulating devices would be applied to the upper sash. They would be practically a duplication, however, of the corresponding parts .ofthe lower sash, the only modifications necessary being those due to the reverse osition of the upper sash with relation to :t e .lower, and hence we have not deemed it necessary to show the upper sash in thedrawings.

In some cases we might find it desirable to dispense with the positive control of the rods so far as theiroutward movements is concerned and simply have them pressed out by yielding pressure and capableof being-drawn in when the sash is to be swung on its horizontal pivots. Sucha construction is shown in Fi 6 where the rods are provided with thum pieces 8 projecting through an elongatedopening in the frame bar and-are normally forced apart by an interposed spring 8 though capable of being drawn together to draw the guidebars out of theguides.
